I think they're 50 volt rated or above, more than adequate. You'll find some are larger than the originals. Not a problem. Don't cut the wires too short.

The seller, Cricklewood Electronics will probably not stock the 0.56uF value. I can let you have a couple if you need them.

Thanks Geoff. I'm gonna try desolder everything tomorrow, measure all the caps, make a list and see how I go. Cricklewood is not far from me so may just pop down there. Let's see if I need 0.56uF and if so will contact you for a price etc. Thanks.

Yes I did notice that they have cap sets for a range of crossovers but not for the Kef one I have. Once I get all the caps off I'll see how I go with either Cricklewood or Falcon.

I suspect I'm overthinking all of this, it is probably all very easy replacing the caps.

I'd not desolder until you have new parts to fit. It'll save having to keep referring to photos or diagrams to recall where bits went. Don't bother measuring the caps, even if they measure OK, their life expectancy is limited and replacing all is the best route. They are after all, forty years old.

You won't need a price for the 0.56uF. They're free.

I'm pretty certain Falcon will be dearer than Cricklewood Electronics.

Yes. Changing caps is dead easy on these. Disconnect the crossover and take it right out, it's much easier that way. To disconnect the tweeter wires, just pull back the small piece of sleeving to expose the soldered joint. You may need some heat shrink sleeving to replace these.

it is in my book,if your going to change the caps that work you might as well get them as close to the original designed value as possible no? otherwise why change them?
but then im fussy about things like that lol

I'll do a price comparison and see what the differences are. If not too much I'll go for the higher spec ones - at the very least when/if I sell the speakers I can say 'audiophile' caps have been used.

But anyway this is only a fun learning project - I really don't need more speakers. My wife was amused when I told her I had got yet another set of speakers - this would be my 6th set. But she could not argue against £12.50.
